Triggering on a specified pulse width
Use this procedure to set the oscilloscope to trigger on a specified signal pulse condition. Y
ou can trigger when a pulse is less than, greater
than, equal to, or not equal to a set time period (width). The minimum pulse width setting is 1 ns. See Available trigger types on page 53.
Pulse width triggering is most often used to troubleshoot or analyze digital signals.
1. Push the Trigger Menu front-panel button.
2. Push the T
ype side-menu button.
3. Use the Multipurpose knob to select and click Pulse Width.
4. Push the Source side-menu button and use the Multipurpose knob to select and click the channel to use as the trigger signal source.
5. Push the Polarity side-menu button and use the Multipurpose knob to select and click the pulse polarity (positive or negative) to
trigger on.
6. Push the Threshold side-menu button and use the Multipurpose knob to select and click the trigger level entry method:
• Click the threshold field and use the Multipurpose knob to manually set the trigger level.
• Click Choose Preset and use the Multipurpose knob to set the trigger level to a predefined signal logic family level (TTL, CMOS,
ECL, and so on) or to 0.
• Click Set to 50% to set the trigger level to 50% of the signal peak-to-peak level.
7. Push -More- Page 1/2 side-menu button.
8. Push the Trigger When side-menu button and use the Multipurpose knob to select and click the pulse width condition on which to
trigger. Then use the Multipurpose knob to enter the pulse width time parameter.
Triggering on a runt pulse
Use this procedure to set the oscilloscope to trigger when a runt pulse occurs. You can also trigger when a runt pulse is less than, greater
than, equal to, or not equal to a set time period (width).
A runt pulse is a pulse that crosses one threshold level but fails to cross a second threshold before recrossing the first. Therefore, a runt
trigger needs two threshold levels to define the two levels that a signal must pass through to be considered a valid (nonrunt) signal. See
Available trigger types on page 53.
Runt pulse triggering is most often used to troubleshoot or analyze digital signals.
The minimum runt pulse width setting is 1 ns.
1. Push the Trigger Menu front-panel button.
